Instant Pot 12 Cup Rice and Grain Cooker
Medium-high risk; stainless steel pot with no nonstick layer reported.
The 12-cup model uses a stainless steel pot without nonstick coating, avoiding Teflon-family coating-based PFAS exposure. Instant Pot provides no PFAS disclosure or third-party certification.

What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Stainless steel corrosion and metal leaching
Stainless steel is stable under normal rice-cooking conditions, but prolonged contact with hard water, salt, or acidic ingredients can initiate pitting corrosion; this risk is low under recommended use but increases if pot is not dried promptly or stored wet.
Silicone gasket degradation and off-gassing
The silicone seals around the lid and pressure valve may off-gas volatile compounds or absorb food odors over time; exposure is limited because gaskets are not submerged, but worn or discolored gaskets should be replaced to prevent condensate pooling.
Bacterial growth in water reservoir or seal cavities
If the water tank or seal grooves are not dried and cleaned regularly, standing water can promote bacterial and mold growth; this is a maintenance issue rather than a material defect, but poor cleaning practices increase risk.
What’s reassuring
Bare uncoated material
Recorded as a bare, uncoated material with no surface coating or treatment.
Plastic housing and control panel leaching
The plastic exterior and button components are not food-contact surfaces and are exposed to low heat during normal operation; no known leaching hazard from these materials under standard use, though prolonged steam exposure near vents could theoretically affect nearby plastic.
Thermal stability and steam safety
Stainless steel does not degrade at rice-cooker operating temperatures; no known risk of fume release or coating failure during normal heating or steaming cycles.
The full breakdown
What it's made of and why it matters
The Instant Pot 12 Cup Rice Cooker uses a stainless steel inner pot with no Teflon-family coating (Teflon-type coating/Teflon) nonstick coating, which eliminates the risk of thermal decomposition fumes at high heat. Stainless steel is chemically inert under normal cooking conditions and does not leach metals into food at typical rice-cooking temperatures (under 212°F). The exterior housing and controls are plastic and silicone; these are not in direct food contact and present minimal leaching risk if kept dry and not overheated during steam release cycles.
The brand's record and disclosure
Instant Pot has not published detailed material safety disclosures, PFAS testing results, or third-party certifications (NSF, FDA pre-market review) for this rice cooker model. The company's silence on PFAS sourcing is notable given that stainless steel manufacturing and water-contact seals sometimes involve PFAS-based treatments; Instant Pot has not clarified whether its components or gaskets contain PFAS. No major recalls or safety violations specific to this rice cooker model are on record, though the brand's general lack of transparency on chemical sourcing is a concern for safety-conscious buyers.
How it compares in its category
Rice cookers with stainless steel pots present lower concern than models with aluminum or non-stick-coated pots regarding thermal stability and metal leaching. However, many competing brands (Zojirushi, Tiger, Cuckoo) publish material certifications or NSF marks; Instant Pot does not. The Instant Pot's price point and brand popularity are strong, but it trades some transparency for consumer convenience, making it a middle-ground choice if you prioritize durability and non-stick avoidance over detailed material sourcing.
If you buy it
Rinse the stainless steel pot before first use and inspect gaskets and silicone seals for any off-gassing odor (should fade within one cycle). Use distilled or filtered water to prevent mineral buildup and corrosion over time; hard-water deposits can etch stainless steel and harbor bacteria. Replace silicone gaskets if they crack, discolor, or retain odor after cleaning, as degraded seals may allow steam and condensate to pool. Avoid extended exposure to acidic grains or liquids (e.g., vinegar-soaked rice) as these can micro-etch the pot surface over years of use.
